2.02 OPTIONAL COMPONENTS
A. BRAZED PLATE CONDENSER
1. Water and glycol cooled systems shall employ a brazed plate heat exchanger. The
condenser shall be equipped with clean-out plugs. Standard pressure rating shall be 450
psig (3102 kPa).
B. WATER REGULATING VALVES
1. Water and glycol cooled systems shall utilize two-way or three-way valves to regulate the
amount of water or glycol supplied to the condenser in response to refrigerant discharge
pressure. The standard valve pressure rating shall be 400 psig (2758 kPa).
C. FLOORSTAND
1. The heavy gauge floorstand shall raise the unit above the subfloor to match the height of
the raised floor. Floorstands shall ship loose and be equipped with air deflectors and for
optimal air distribution. Heights available from 12" (305mm) to 24" (610mm) on the
FM35 and from 18" (457mm) to 24" (610mm) on the FM50 in 3" (76mm) increments and
shall be adjustable +/- 1.5". Threaded pedestals shall provide adjustment. Vibration
absorbing pads shall be included.
D. SUB-BASE
1. A sub-base shall raise the height of upflow units for electrical wiring and piping access.
The height shall be 10” (254mm). Access panels shall be provided in the front and rear of
the sub-base with 1/4 turn latches for removal.
E. PLENUMS
1. A discharge plenum shall mount on top of an upflow unit to direct and distribute
conditioned air. The plenum shall be manually adjustable with double deflecting grilles
provided on 2, 3 or 4 sides.
2. On downflow configurations, a plenum shall raise the FM35 by 12” (356mm) and the
FM50 by 18” (457mm) and discharge air horizontally from the front of the plenum.
F. DISCHARGE DUCT COLLAR
1. A 1” (25 mm) duct flange shall be provided for field installation on a unit to provide
convenient connection to external ductwork.
